Crossy Posted October 3, 2021 Share Posted October 3, 2021 Some investors would seem to think that it is:- Tiny Devon village with population of 286 will be connected to MOROCCO by the world's longest undersea cable in £16bn plan to bring wind and solar energy from 2,360miles away to power seven million British homes. Village of Alverdiscott, Devon, is one end of £16billion undersea cable project The village, of 286 people, will be connected to a line running to Morocco Scheme will import solar and wind-generated energy to power seven million homes by 2030. https://www.dailymail.co.uk/news/article-10046765/Tiny-Devon-village-population-286-connected-MOROCCO.html 2 Link to comment Share on other sites More sharing options...

But that sounds like a lot of voltage drop by the time it reaches UK, or does the change to HT DC alleviate that problem? 5 1 Link to comment Share on other sites More sharing options...

Yeah, the link is HV DC but there's still going to be a not-insignificant energy loss warming up the ocean. Link to comment Share on other sites More sharing options...
Popular Post Will B Good Posted October 3, 2021 Popular Post Share Posted October 3, 2021 Like all electricity transmission it must be done at very high voltages so the current and heating loss is as low as possible. I guess the cost and reliability then all depends on the grade and quality of the cabling. You would like to think someone, somewhere knows what they are doing! 3 Link to comment Share on other sites More sharing options...

HV DC is best! No skin-effect and no radiated losses, also no worries about grid synchronisation. 1 3 Link to comment Share on other sites More sharing options...

Popular Post gk10012001 Posted October 3, 2021 Popular Post Share Posted October 3, 2021 "worth"... depends how it is defined. Lots of things are involved. Large capital investment to build or install the systems, that take 10 years to get the ROI Return on Investment is usually too long for most investors or cities or countries to buy into. And that is not even considering repairs and maintenance. As for transmission, high current DC transmission is making a come back. I worked on some high power systems and motors for large ships so picked up a few research things along the way. Switching and converting the DC in addition to the transmission has improved greatly. Monsterous capability IGBTs for example. It really is a fascinating field. https://en.wikipedia.org/wiki/High-voltage_direct_current 4 Link to comment Share on other sites More sharing options...

We didn’t mean a short scale 16Bn ( 10 to the power 9) thus as you correctly calculated £2285. We meant the UK long scale (10 to the power 12) thus £2,285,000 per home !!! Maybe they are factoring in a 10 year period, therefore only £228.50 per home, but of course no maintenance required. 1 Link to comment Share on other sites More sharing options...
Popular Post Thaifish Posted October 3, 2021 Popular Post Share Posted October 3, 2021 Ozz planning a similar HVDC Solar project...errr umm the Pommy cable is 2360miles=3798km. The Ozzy cable will be 3,800km=2361miles. If I was Trump I would be doing another Term in office with that number!! 3 Link to comment Share on other sites More sharing options...

tjo o tjim Posted October 4, 2021 Share Posted October 4, 2021 For the UK, and the way the project is designed, it is a great solution. For Morocco it is a great project. Some real innovations should come from this project. It will have a lower cost of energy than Hinkley Point. But, as a general solution you want to have as much generation and storage close to demand as possible. This works well because it adds geographical diversification for wind, and latitude and cloud cover based efficacy improvements for solar. Unfortunately the project is unlikely to use the solar shading to provide agricultural opportunities in the region. Link to comment Share on other sites More sharing options...

Srikcir Posted October 10, 2021 Share Posted October 10, 2021 Morocco has among the one of the highest rate of solar insolation in the world and has launched one of the largest solar energy projects at an estimated $9 billion. See Wikipedia What's the urgency that energy imported from England via undersea cable is a priority and with such a high cost? Sounds like Thai "economics" at play. 2 1 Link to comment Share on other sites More sharing options...

Popular Post Muhendis Posted October 10, 2021 Popular Post Share Posted October 10, 2021 The cable route on the picture/map seems to go within the territorial waters of Portugal and Spain. I wonder if that's wise. Also how stable is Morocco politically. Also why go the long way round Cornwall to Barnstable when the nearest point is somewhere like Plymouth and would would save a few hundred miles of very expensive wire. Note to self. Must get shares in the copper supplier company. 4 Link to comment Share on other sites More sharing options...

bluejets Posted October 10, 2021 Share Posted October 10, 2021 New Zealand have used HVDC transmission for donkeys years but this solar/wind thing seems a bit extreme when one considers the distance involved. Wonder if it's a reality or just someones idea of rounding up a few quick bucks while "green" is the flavour of the month ( or moreso) I'd be keeping my money on my own shed roof. 1 Link to comment Share on other sites More sharing options...
Muhendis Posted October 10, 2021 Share Posted October 10, 2021 9 minutes ago, bluejets said: I'd be keeping my money on my own shed roof. Yes' I am in tune with that sentiment. I think solar micro grids (+ storage) are an approach worth considering. The trouble with that is there are many who live in flats and apartments who don't have their own roof and many home owners whose roof is leaning in the wrong direction, however that's where solar and wind farms come in. Since those will probably never be sufficient for the UKs power needs then importing from Morocco is not such a bad idea. Link to comment Share on other sites More sharing options...

rickudon Posted October 10, 2021 Share Posted October 10, 2021 The economics of selling it to the UK is because electricity prices in UK are higher than Europe. But does sound a bit of a gamble. Maybe they want the same price as the new nuclear station (Hinckley Point?) will get. But apparently the UK intends on cutting green taxes on Electricity generation and shift it to Gas and other fossil fuels. Logical if you want to make people use electricity instead of gas.
